Sibi Sankar 7ad18bb5c2 soc: qcom: cmd-db: Fix compilation error when CMD_DB is disabled
If CONFIG_QCOM_COMMAND_DB=n the following compilation errors will be
seen. Fix this by including the appropriate linux headers.

./include/soc/qcom/cmd-db.h: In function ‘cmd_db_read_aux_data’:
./include/soc/qcom/cmd-db.h: error: implicit declaration of function ‘ERR_PTR’;
